Abstract: The paper is devoted to mathematical method of holding task-based CTF contests under threat of DDoS attack against organizers' servers. For the purpose, a decentralized protocol is proposed where a part of organizer role is distributed among participants. There are some important security requirements to the protocol due to the competitive nature of CTF contests. The result protocol meets these requirements. Its stability against considered attacks is researched. Directions of further research are described.

Keywords: distributed protocol, secure computation, fault-tolerant system.
